【摘要】 根据齿轮FG(Formate Generated)加工方法中的机床各部件运动关系,建立了坐标系模型,推导了虚拟坐标变换。分别运用抛物线型刀具和直线型刀具加工大小齿轮,在有助于齿面修形的同时保证了齿轮的高生产率。在MATLAB中画出了单个大小齿轮的齿廓图,进而将数据导入Creo中建立了实体螺旋伞齿轮模型,为后续的有限元分析奠定了基础。更多还原

【Abstract】 According to the relationships among the movements of machine parts in the method of FG,the system model is established,and a virtual coordinate transformation is deduced. Gears and pinions are respectively made by using parabolic and linear blade profiles. This is benefical to modify the tooth surface and keep high productivity.The profiles of pinion and gear are drawn in MATLAB,and the data is imported to establish the model of spiral bevel gears in Creo,which has laid a foundation for the subsequent finite element analysis.更多还原
